Fig. 8 is aside view, and Fig. 9 an edge view, of a button-head blank, of leather-board or other suitable ma-y terial. 'Fig. 10 is a side view of a finished button. Fig. 11 isahorizontal section of the feed-rol1ers and parts immediately adjacent thereto.. Fig. 12 is a side view of the abutment D, into which the wire descends. Fig. 13 is a transverse section of themachine, taken through the feed-rollers. Fig. 14 is avertical and transverse section of the machine, taken through the springs that forceapart he; jaws K, hereinafter described,l such section 'showing such jaws. Fig.'15 is anotheitsnch sec- 'tion taken through the button-head, blank passage or raceway, land the plunger thereof. vFig-16 is a horizontal section' of the jaws K K, itvbeing taken through the pin G. 4 5 The machine on which my improvement or invention is based is for reducing wire into 4button-eyes in the form of a staple, and for pressing each into a head, and at'the same time imparting form to such head .The main 5o characteristics of such a machine are mecham ism for intermittently feeding thewireto a slaan No. amiss. '(Nt modal.)

stopor abutment, mechan-isni for separating from the strip of wire a piece of it of sufficient length for an eye, mechanism' for bending' such eye'into the form of,a staple, mechan- 5.5. ism for grasping and holding the eye after such formation of it, mechanism .for guiding and feeding the head-blanks into themachine,

and lmechanism for forcing each of such blanks. v

upon an eye, so as -t'o give form to the 4blank, 6o

and at the same time effect the passage o f the legsofthe eye into it, the said blank.

Before proceeding-to a further enplaiiation of -my improved or newmachine, it may' be. remarked that one distinguishing. feature of it 65 is its mechanism for cutting the wire obliquely to .its axis rather than'square thereto, and

-bending'tfinzthe-p'lane of. the conj-ugateaxesf.

of its terminal ellipses,-suc l 1oblique cutis bef. ing shown at ax kin '-Fig." i.' Oneach piece or eye-blank being subsequently bentaround in the form of a staple, the Obliquity of one end o f it will stand the opposite way of that of the other, 4as will bel'seen by inspection of Fig. 5, wherein the obliquities' jor faces of cut are shown at t* and y". While the button-head is being forced upon the' two legs of the eye, the said obliquities canse the said legs to turn or be bent or to diverge opposite ways, as shown in Fig. 6; whereby each leg becomes, to a certain extent, hooked within .the head,'and as a consequence the eye is held withl great firmness within such head.

The Obliquity at each end of the eye iself liptical in shape, and the wire -composing the eye-isbent by the machine inthe plane of the 1 .conjugate 4axes ofthe two ellipses. Were the wire bent `1in-the plane of the transverse aires ofthe two ellipses both obliquitieswould stand in the same direction, and of course.-;the legs of the eye in passing into a buttonhead would not spreader be deiiected-in opposite ways, but wouldhein thasame lway.

Besides the characteristics as hereinbefore mentioned, my said machine is provided with means of expelling from-it each button after its completion therein, as explained. f

'lathe drawings,I A denotes the bed-plate of: the machine, such plate being provided .with

a main shaft, B, and' an auxiliary-'jshaft,i C,

they being duly journaled in boxes or bearings lc c and l b. A. bevelgeanaxed on the main-i shaft, engages with a similar gear, d, fastened on the auxiliary shaft, which stands at right angles to the main shaft. At one end of the main shaft .there is a ily-wheel, e, and at the other, and a loose pulley, g.

The wire for the formation of the buttoneyes is shown at h as going il rough a stationary guide, i, and thence between twofeedrollers, k l, on the shaft o, one of which is a grooved pulley,-m, about which, and another such pulley, m2, on the shaft C, an endlesscrossed belt,v a', works. The shaft p of the other roller is pivoted at one end to a standard or post, q, in orderthat such shaft may be turned or swung outwardly horizontally. The roller Z turns .freely on its shaft p, through which and a sprin g, r, fixed to the post,a headed screw, s, extends, and has screwed upon it a hand-nut, t. By revolving the said nut the grip of the feed-rollers om the wire maybe in.- creased or diminished, as occasion may require. In descending, the wire at its lowerend will be forced into contact with and arrested by a stop or abutment, D, which basin it an augular recess, u, as shown in Fig. 13, such-recess being toy centralineA the wire and to stop itin its descent. Ou the wire beingstopped by the abutment the yfeed-rollers will continue to re. volve, but will slip on the wire and will not again move it until after a. piece may have been separated from the wire andconverted into a button-eye and iusertedin aibuttonhead. Before entering the said recess the wire passes through la. stationary tubular guide, E, whose lower end is oblique or inclined, as represented, it being to operate with a cutter, F, properly formed for it, while being moved underneath or across the said guide, to cut the wire obliqucly toits axis, as hereinbefore menv tioned. Each eye-blank severed 'om the wire has its ends wedge-shaped, as shown. The said cutter F not only performs the function of removing a blank -from the strip of wire, but that of bending the said blank at its middle around a pin, G, arranged horizontally, the wire being, by acurved notch, v, in the f cutter, bent into the form of a staple. The cutev ter projects from and is-attached to a. slide, H,

adapted to move rectilinearly. It is impelled forward by a lever, I, which is moved one way by aicam, w, fixed on the shaft C. A spring, properlyv applied to the bed-plate and the slide H, serves to retract the slide, and to keep a friction-roller, y, on the lever against the cam w.

After the blank has been bent, as described,

two jaws, K K, are advanced horizontally to- .ward and grasp it between thenn,lea,ving extending from them suihcient portions ofthe legs of the eye to enter a button-head blank. (See Fig. 16.) Y The jaws slide horizontally, and are forced toward ,each other by'two levers,L, ar-

ranged as represented, and actuated by cams z,iixed onthe driving-shan?. Each-lever L has in its arm' that is next the ljaws aserew, a',

vthat screws through the and -reeeivesin a.

or thcreabout, there is a fast pulley, f,

socket at its end a-pitman, b', extending from Each jaw is provided with avspring, d', for

roller e' in the lever L against the camz.

The buttonhead blanks, being short cylinders of leather-board, are forced successively by suitable mechanisminto a guide-path or raceway, f ',arranged above and extending over into a cylindrical chamber, g', arranged or formed in thetwo jaws. Extending within this oha'mber is the header M, in whose inner end is a cup-shaped recess, or -concavity, h. After is advanced, and not only forces aheadfblank yupon'the legs of the eye, but imparts Vto the said blank asenii-globular form, or an'approximation thereto. The header M is fixed in a carrier, N, which is Operated by an eccentric, z", carried by the driving or main shaft, such carrier being adapted to slide rectilinearly back and forth. Itis connected with the eccentric by' a collar, k', thereon, a revoluble screw,"'i', and a jointpiece, m', the latter being jointed, as shown,- to the carrier. The screw screws into the jointpiece, and is rcvoluble wit-hin the collar, and is held' represented in Fig. 4. y

` The button-head-blank plunger isshown at O, it being reciprocatedor moved vertically, as occasion may require, by'a lever, P, which, fulcrumed in a post, Q, is properly jointed to the plunger and bears upon a cam, R, fixed on .the main shaft. This plunger, arranged as shown, is adapted to slide vertically and is adjustable in a carrier, o,`which is jointed to the lever and provided with a setfscrew, p', for

part of the groove af, in which the plunger works, there is al spring, b, which holds the head-blank, so that it shall not fall out oftheraceway before the jaws are ready to receive such blank. L

The pin G projects from and. is carried by one of the jaws K, and enters a recess or hole, q', in the other jaw, when thefjaws are moved toward each other, they holding the piu firmly after which they close upon the eye and hold it securely vwhile the buttonhead blank is being forced upon it, the said eye. Next the jaws move apart, so as to draw th'e pin G out ofthe button-eye, and the header retreats. In moving backward through' the button-eye the pin G draws the eye against a stationary stud or pin, r', which extends from. the part in which the jaws slide. This' stud or pin r serves to hold the button until the pin G is drawn out of theeyef Ou thepin passing out of the eye, the buttonis free to' fall or drop out of the machine.

I would observe that l do not claim a butv.pieces to fornil the eyes of the buttons is cut from a strip of wire at right angles to its axis,
